Optimize your onboard air system with the Kleinn 2131 sealed 12-volt automatic air pressure switch, engineered to turn your air compressor on at 100 PSI and off at 130 PSI with a standard 5 percent variance tolerance. Perfectly matched for use with the Kleinn 6270RC compressor in the HK3-HK4 kits and a universal fit for various heavy-duty pneumatic applications, this switch receives 12-volt ignition power to efficiently signal a required SPDT 30-amp relay (such as Kleinn Model 340) to automate your compressor operations safely under a 20-amp maximum load. For ultimate system protection against switch failure and to prevent compressor burnout, it is highly recommended to pair this unit with a 155 PSI safety relief valve (Kleinn SKU 52155) installed directly on your air tank.
